Therefore, an already optimised STL-file is needed as a Start Space. This can be exported directly from the post processing and be selected as a Start Space by clicking on the browse button. Therefore, the unit of the exported STL-file needs to be in meters (SI-Units). In most cases the Strut Density and Shape Quality settings must be changed as well using the Advanced User Settings. For a restart the same resolution level and number of to be completed iterations have to be filled in. You can find a Tutorial to how to perform a Restart here.
This way a two-stage optimisation is also possible. For a two-stage optimisation the resolution level and number of iterations must be chosen wisely and will need some fine tuning.

All areas applied with a boundary condition are automatically Interfaces. With an Interface the surface will grow a little bit beyond the Design Space boundaries to ensure a trouble-free and clean intersection. It is also possible to detect all Non-Design Space surfaces which are at the same time Design Space limits and let them grow automatically. This option results in a different connection between the Design Space and the Non-Design Spaces/Interfaces. Both results can be viewed here.
If the connection of the automatic Non-Design Growth is preferred, it can be activated with the following command:
...
Sometimes this can lead to issues which are described here.
